SHEET-METAL noonFnAME 'ooivsclnnuefrroiv This inventionfrelates tothelatch plates for locks of variouskinds and classes and k particularly todevices of this class mounted 1n and constituting part of the door frameJect-matterof my prior application filedl construction and in connectionwith which the latch bolt of a lock mounted on a door is adapted tooperate; and the object of the invention is to provide a. latch platewith means for quickly attaching the same to the door .f frame andrsupporting the' same in an aper- Y ture 1n said door frame 1n suchmanner as to come in alinement with the latch bolt of alock mounted onthe door hingedly 'sup'- ported in said door frame, the mounting ofsaid'latch bolt being such as to permit of the quick attachment anddetachment thereof, at will, and further to permit ofvits adjustment orreversing of the position thereof in the door frame to compensate forvarying heights of the latch bolt on thedoor to bring theplatch boltreceiving aperture ofsaid plate in proper alinement withthe bolt of thedoor; a further object being to provide a. latch device of the classspecified which is primarily adapted for use in sheet metal door frames,the door frame being fashioned tok seat said plate with theouter facethereof flushV with the outer face of the adjacent walls of the doorframe, said plate having a movable device or devices adapted to engagethe door frame to retain the same againsty accidental displacement; afurther object being to provide a-klatchplate, which by virtue of itsconstruction vand use will permit of the construction' of standard sheetmetal door stock'frames in stock sizes with a [universal adaptation of alatch plate to said standard stock sized door frames, eliminating thenecessity of constructing door frames specially for eachindividualfbuilding construction at the time of giving contractstherefor as is the usual custom, said standard frames being providedwith an aperture of universal common form and dimensions to permit ofthe 1 provided with one elongated'flatch bolty remounting of suitablelatch plates in connection therewith;v and with these and otherobjects'in view, thev invention consists in a device of the class andfor the purpose speci- `fied, which is simple in constructionand opingyanother modification.

This invention constitutes divisional sub- J une 22, 1926,'SerialNo..117,679, and is fully disclosed in the following specificatiomofwhich the accompanying drawing forms a part, in which the separatepartsv Iof my improvement are designated by suitable referencecharacters in each of the views, and in whichz Y' Fig.' 1 is aperspective view. of a part ofa door frame showing one ofV my vimprovedlatch plates mounted in connection therewith.' v Y Figxfla is aviewsimilar toFig. v1 but showing the latchplate mounted in areverseposition, l

Fig. 2 is a partial section on the-line '2--2 of Fig. land on anenlargedscale. y Fig.I 3 is a back view of the latch plate detached andindicating the manner -ofy its mounting inl a-door frame. y

Fig. 4 is a view similar to Fig. 2Y but showing ai modification and,

Fig. 5 is a view similar tofFig. 4 but show-l vIn Fig. 1 of the drawing,I have shown for thepurpose of illustrating one method of carrying myinvention into eect a part of a sheet metal door framelwhich may be ofany conventional cross sectional 4form 11 representing the door stopportion vof the frame, limiting the swinging movement of the door in'one' direction, which formsl at one side thereof, a face 12 to receivethe free outer face or edge of the door hingedly lsupported' in the`frame 'in the usual manner. The face 12'of the frame 10 at apredetermined distance above the to receive a latch ceiving aperture 15which extendscloser to one end 16 of the plate 12 than the other kendvthe height of said aperyture 14 in the vdoor frame'lO may be raiseddescribed v and y L yfloor is provided f with' an aperture 13 preferablyelongatedV its rear side with a strip 19'secured thereto in anydesiredmanner, the edge of said strip projecting beyond the beveled endof the plate 14 to engage the inner face of the part 12 of the frame toretain the plate 14er the end portion 16 thereof ag-ainst displacement,

while a lock or catch device 21 is pivoted to the other end 17 of theplate 14 as seen lat 22 and adapted to extend onto the inner face ofthepart 12 of the frame 10 within theaper-v ture 13 to secure the end 17of the plate 14 against displacement. The member 21 may be moved fromthe position shown in dottedV lines in Fig. 3 of the drawing to thatshown in full lines in Fig. 3 and also in Fig. 2.of the drawing, by asuitable tool passed inwardly through the aperture 15 in the plate 14.

In placing the plate 14 in position in the aperture 13 of the frame, itwill be understood that the end portion 16 is rst inserted into theaperture 13 adjacent one endthereof, after which the fotherend 17 of theplate 1'4 is swung into position with the member 21 in the dotted lineposition shown in Fig. 3 of the drawing, and said member is then turnedinto the position shown in full: linesas above stated.

In Fig. 4 of thedrawing, I haveshown a modification wherein the part 121'of a door frame, instead of being provided with the beveled faces asat 18 in Fig. 2 of the drawing, is offset to form stops 23 and, 24 tolimit the inward movement of-a latch plate 25 and to support the latchplate flush with the outer face of the part 12a as clearly seen 4in Fig.4 of the "drawing, the inner face of the latch plate 25 being providedadjacent thefends 26 and 27 thereof with springclips Y28 adapted to besprung over the stops 23 and V24 rand toengage the Asame as-seeninFig.r4 to secure the plate 25 against accidental. displacement and yetpermitting ofthe forcible removal of said plateV at will. 'The aperture29'in the plate 25 is arranged in the same'manner` as 'the aperture 15inthe plate .1.4 whereby the 'plate may be reversed intheydcor frame toraise or lower the aperture 29. .Inthe above operation of attaching yanddetaching, the plate'25, it will be understoodthat the spring clips 28are sprung inwardly, and the rounded ends of said clipsfacilfitatethis.l operation.

In Fig. 5..-of .the .dra,wingylifhtweishownv anof the principles seen inFigs. 1 to 3 inclusive and part of that shown in Fig. 4 of the drawing.In this construction, the attaching plate 30 is fashioned at one end toform a V-shaped notch 31 having a projecting inner flange 32 to engagethe inner wall of the door frame, the V-shaped notch engaging a beveledface in the aperture of the door frame as seen in Fig. 2 of the drawing,while the other end of the plate 30 is/provided on its inner end with aspring 33 adapted to engage la stop member-34 on thedoor frame as in theconstruction shown in Fig. 4. .With this form of construction, theaperture V35 in vtheplate 30 will be centralized in that the plate 30cannot be reversed in the door frame in the manner .of the reversal ofthe plates 14 and 25. It will be understood, however, that either theupper or lower end of the plate may be provided with the spring clip 33as may be desired, the door frame being fashioned to -suitthe con- Ystruction employed.l

It will also be understood that my invention is not limited Yto thespecific means herein shown and described for detachably supporting thelatch plate in connection with the door frame, nor to the lspecific,form of said plate and various other changes in and modifications of theconstruction herein shown and described may be made, within .the scopeof the appended claims, without departingy from the spirit of myinvention or sacrificing Aits advantages. n j l I-Iaving fully describedmy invention, what I claim as new and desire to secure by LettersPatent, is Y v 1.- A sheet metal door framevfashionedto standardizethe'manufacture thereof, vone of the side rails of said door frame beingprovided with a latch plate aperture and a latch plate mounted directlyin connection with said door frame and fitting snuglyV in the aperturein the side rail thereof, and means for directly mounting the plate inconnection with said frame in two different .positions of the plate inthe frame. i

2. A sheet metal'door frame `fashioned to standardize the manufacturethereof, one of the side rails of said `door frame being provided with alatch plate aperture and a latch plate mounted fdirectlyvin. connectionwith said doo-r frame, and -fittingsnugly in ,the aperture in the siderail thereof, means for directly mounting the plate in connection withsaid frame in two differentpositions of the plate in the frame,andvopposite walls of said aperture being beveled :outwardly to formseats for correspondingly bevelediedges on said latch plate.

In testimony that'I claim vthe foregoingV as my invention I have signedvmy name .this
